Research Abstract

This study aimed to reveal effects of the number and position of implants which support a partial overdenture (I-POd) on mechanical loads exerted onto the abutment tooth of the denture and on the residual ridge beneath the denture.Two implants were placed at the second premolar (imp1) and the second molar (imp2) position in edentulous area of model. Load onto the abutment tooth was measured by a piezo-electric 3D-force transducer. Load exerted on residual ridge beneath the denture was measured by a tactile sheet-sensor.Measurements were performed in four test conditions as follows: no implants supporting the denture, imp1 supporting the denture, imp2 supporting the denture and imp1 and imp2 supporting the denture.Loads onto the abutment tooth and residual ridge beneath the denture base were significantly associated with the implant number and position of I-POd. Application of implants beneath the denture base contributes to reduce the loads onto the abutment tooth and residual ridge.
